Support evil-mode indicator

[lbolla]

When using evil, an indicator showing which mode is active is usually shown in the modeline.
Zerodark's modeline though hides it (if the theme is loaded after evil).

I'm not using evil, but I will test it locally.

Are you using zerodark-setup-modeline-format?

[lbolla]

@NicolasPetton Yes, I am using zerodark-setup-modeline-format.

ok, I see. Zerodark's modeline format doesn't support evil yet, and I'm not an evil user myself. If you know a custom modeline that does, that should give me enough pointers to get it done.

I implemented it for my personal theme, here: https://github.com/lbolla/emacs-quasi-monochrome/blob/master/quasi-monochrome-theme.el#L278
